Current Location returning 0 - objective-c

Question

My Xcode app that I am developing needs to get the latitude and longitude of the users iOS device. Although currently all I get is 0 for both values. It does not ask for permission to have the location, and I am on a real device not a simulator.
NSLocationAlwaysUsageDescription is in my info.plist
I have also imported CoreLocation and in my .h file
#interface LocationViewController : UIViewController <CLLocationManagerDelegate>
in my .m file
#interface LocationViewController () <CLLocationManagerDelegate>
Here is my code:
#implementation LocationViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self getCurrentLocation];
}
-(CLLocationCoordinate2D) getLocation{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];
return coordinate;
}
- (void)getCurrentLocation{
CLLocationCoordinate2D coordinate = [self getLocation];
NSString *latitude = [NSString stringWithFormat:#"%f", coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:#"%f", coordinate.longitude];
NSLog(#"Latitude = %#", latitude);
NSLog(#"Longitude = %#", longitude);
}

Answer 1

Refer this answer. Hope, this helps.
Make this changes :
-(CLLocationCoordinate2D) getLocation{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager requestWhenInUseAuthorization];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];
return coordinate;
}
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
NSLog(#"Status : %d", status);
}
Goto Settings > Privacy > Location > Your App > Always
And see how 'Status' value gets changes.

Answer 2

Put below before startUpdatingLocation
#ifdef __IPHONE_8_0
if(IS_OS_8_OR_LATER) {
// Use one or the other, not both. Depending on what you put in info.plist
[self.locationManager requestWhenInUseAuthorization];
}
#endif
[self.locationManager startUpdatingLocation];
Also call [self getCurrentLocation]; in viewDidLoad & viewDidAppear both.
It will work.
Also make sure you have entry for requestWhenInUseAuthorization in info.plist file too.
